In Mach engine, we're compiling Dawn using Zig as a C/C++ compiler. Zig provides it's own libc implementation, build system, and system headers.
Dawn today makes use of newer
windows.ui.*.h
headers introduced in more recent Windows versions. However, Zig relies on MinGW for it's system headers and it is not straightforward/desirable to use the official Windows SDK headers: Zig does not have these headers today.Since Dawn does not truly require these headers, we are using a preprocessor directive
DAWN_USE_WINDOWS_UI
to disable this functionality and enable compilation of Dawn with Zig/MinGW compilers.I have based the implementation on the existing
DAWN_USE_X11
andDAWN_USE_WAYLAND
build configuration approaches.Signed-off-by: Stephen Gutekanst stephen@hexops.com
